Maybe infected terrorists are coming to US cities soon. They may even be walking around Washington now! Plague might be the next 911? I will replace my tinfoil hat and renew my subscription to Conspiracy theory magazine. I really don’t think the terrorists are smart enough to think of this.
Never underestimate your enemy. I guess you are not in a war then. News to me.
It would be hard to spread the plague by sending those infected with it into an area. First off, it is spread by fleas, who live on rats, and unless an infected person is bitten by a flea which then bytes an uninfected person. Flea infestations are not that rare in the US, but getting a bunch of them to bite specifically people and then bite other specific people would be tough. People who have the plague are pretty sick and probably not around long enough to share their misery with a lot of others. It was a major problem in Europe because of the living conditions. Those conditions are not prevalent in most of America today.
I am not an expert on the subject and make no claim to be. It’s possible they have found a way to spread it without the rats that carried the fleas, but if that’s the case then all bets are off.
Not smart enough? Ha, they are smart, evil and very patient.
